Application filed January 8, 1914. Serial No. 811,108.

T0 all whom it may concern:

Be it known that l, lVILLiAaI Q. PFAHLER, a citizen. of the UnitedStates, residing at Toledo. in the county of Lucas and State of Ghio,have invented a new and useful Tank-Gutlet, of whichthe following is aspecification; v

This. invention relates plugs for tank outlets.

An object of the present invention is to provide an outlet device orplugv which will allow the tank to be readily drained and at the sametime will prevent foreign material from entering the outlet pipe.

A further object is to provide an outlet device with a storage chamberfor the deposit of the sediment and foreign material which may bepresent in the liquid contents of the tank and thus it will bevprevented from entering the outletl pipe. x

A further object isto-provide a device of the aboveV mentioned typewhich may be readily removed from the tankv for the purpose of cleaningand to ascertainthe conditionthereof. f f I,

'lith the foregoing and other objects in view `which willf appearfas thedescription proceeds, the inventionfresides in lthevcom-l bination andarrangement. of-fparts andxin thedetails of eonstructin hereinafterdescribed `and claimed, Ait being understood that changes in thepreciseembodiment of the invention herein disclosed; can. be made toimprovements in within the scope of what is claimed, with--v outdeparting: from thespritpf'.theirv ventio i" u f In the drawingsaccompanying thisspecification and forming a; part thereof, thepreferred embodiment of f my invention is illustrated, in which y Figure1 is a view in elevation of my device taken through the longitudinalvaxis thereof and illustrating a portion ofthetank to which it issecured. Fig. 2 is a sectional view taken on'the line 2-2 of Fig. 1.

Referring now to the drawings in which similar reference numeralsdesignate analogous elements .throughouf the several Hgures, 3represents the side wall of a tank and 4 the bottom. The bottom 4 of thetank is provided with the outlet opening 5 rivets Gr'orother-equivalentmeans, is the plug attaching member-7 which includes the .the said plugattaching member is rigidly secured to the tank and effects a'liquidtight juncture therewith. i

T he plug 10 which is detachably secured to the plug attaching member 8includes@ centralv pipe-like body portion 11 whichis threaded at itslower` extremity as at 12 and to which lower extremity maybe secured apipe for the conducting of the liquid which flows from the tanktoany'desired point. It is to be noted that the device herein disclosedis particularly fadapted for use with gasolene tanks in which apipe-like body portion 11 will-communicate with the carbureter and thusit is of prime importance to prevent any foreign lmaterial from enteringthe pipe-like body portion `as the same would eventually find its wayto' and llodgein the needle valve of the carbureter proper and efficientworking the concentric upst'anding flan-ges 14 and 15. 'The outermostflange l5 is externally thread-` ed and is spaced' a slight-distancefrom the extreme edge of the diskso as to threadedly engage the sleeve 8and with the periph- .lill .edge thereof lying flush with the outersurface of the sleeve, The outer flange 15 is -1 of relatively lessheight than the inner flange 14 so that shouldfor any reason sediment icollect upon the top edge of the flange .15 it will not be liable togravitate into the annular opening between the flange 14 and thel bodyportion 11. Rigidly secured to the outer surface of the liange or sleeve14 is the'fwire screen 16 which is dome-shaped as at 18 at its upperextremity and which is of suliciently fine mesh to practically excludeall foreign material of such dimensions as l would interfere with theproper working of the valves of a carbureter. The wire screen 16 iscylindrical in outline as illustrated in Fig. 2 and completely inclosesand protects the opening 19 which extends through the pipe-like bodyportion 1 1. The

'space intermediate the fianges'ory sleeves 14 and 15 forms an outlyingcollecting receptacle 2O in which the foreign material will collectwhich is of too large dimensions to pass through the screen 16. Thespace between and defined by the opstanding liange 14 and the bodyportion 11 forms a recepta'cle 21 in which is adapted to collect anyline particles which may pass through the screen 16. However, thecollection of material within thereceptacle 21is .a remote l contingencyas the screen is made sufficiently fine' to exclude all articles' frompassing therethrough. In order that the material collected within theoutlying and annular compartment QOVmay bedrained therefrom withoutrequiring the removal of the entire plug,'a,pet cock` 22 is providedcommunicating with the bottom of the receptacle and which may be openedeither for the purpose of' draining the'sediment which ymay have 4becomedeposited within the said receptacle or for the draining of the entirecontents of the tank as may be desired. A The body portion l1 4 whichincludes the outlet central opening l19 is of suiiicient length so as toextend above the bottom 4 of the tank so as to--further preventV thepassing of foreign material through the `screen which .might happen bythe force ofthe current were the said* body portion to terminate belowthe bottom 4 of the tank. The disk 13 is providedfwith the enlargedportion 23 which presents a wrench engageable surface and.

curing thefsame to and extending below the side walls ofa tank opening,a plug detachably secured to the said sleeve and including a centrallyextending pipe-like body portion,

an outstanding disk carried by said bo'dy portion intermediate its ends,the said disk provided with two concentric upstanding sleeves, theoutermost sleeve being detachably secured to the said plugattaching andsupporting member sleeve, the said pipe body .portion extending abovethe plug attaching member when secured thereto, the lannular spacebetween the said upstanding sleeves of the disk forming a dirtcollecting receptacle, a cylindrical screen carried by and affixed tothe innermost disk sleeve and extending above and encompassing the saidpipe body portion, and means communicating with the said dirt receivingreceptacle adapted to drain the same.

2. A device of vthe class described comprising a sleeve, means forsecuring the same to the bottom of a tank, a pipe provided with a diskintermediate its ends, the said disk engaging the said sleeve with thepipe extending above the bottom wall of the tank,l

said disk provided with a concentric upstanding flange, a wire screencarried by said iange spaced from the upstanding portion of the pipeandv housing the same therein, the annular space between the screen andthe said sleeve forming a dirt collecting receptacle, the annular spaceintermediate the pipe and the said annular flange defining a secondforeign material collecting receptacle. j

In testimony that I.claim the foregoing as my own, I have hereto aixedmy signature in the ,presence of two witnesses.
